Abstract

Aspects of a method and system for adaptive deblocking for AVS1-P2 are provided. An AVS decoder may receive a bitstream comprising filtering parameters and plural macroblocks. The plural macroblocks may be decoded to form decoded pictures to be processed based on the filtering parameters and corresponding adjusted quantization parameters (adj_qp) calculated from the perspective decoded pictures. The adj_qp of a decoded picture may be determined based on the type of the decoded picture and associated reference pictures of the decoded picture. A filtering strength may be determined and/or adjusted based on the filtering parameters, the slice boundary information, the adj_qp, and user control information. The decoded picture may be filtered via an outer-loop deblocking filter with the determined filtering strength to reduce macroblock and/or slice boundary artifacts of the decoded picture. The outer-loop deblocking filter may be turned on or off in responsive to the determined filter strength level.
